There are many types of landforms that make up our worlds ecosystems. A type of landform that we have all heard of is a valley. Valleys can be defined as an area of lowland between ranges of hills or mountains. A recent discovery in a valley in China has given scientists a new idea on how dinosaurs might have looked. They found a dinosaur tail encased in amber that was covered in feathers. Scientists are now beginning to think that many of our dinosaur friends were covered with feathers!
